DISK WHEEL.

' Application filed May 15,

To all'whom it may concern:

Be it known that I, ELMER .L. Aonnn, a'c1tizen of the UnitedStates, residing at Chicago, in the county of Cook and State of Illinois, havein'v'ented. a new and uscful Improvement in Disk Wheels, of which the following is a specification.`

`rIhis invention relates to disk Wheels and l is fully described in'` the following specifivin Fig. 1;

In the embodiment shown in Fig. 1, the Wheel consists of a rimv '10 secured upon the flange 11 of the disk 12Abyl any suitable means such as spot Welding. The. disk 12\ is secured upon thev hub 13 by means of an adapter 14 and bolt 15 passing'through the disk, adapter, and hub. Y

Conical cupshaped projections 1Gare arf ranged preferably concentrically about the' axis ofthe hub, and are raised from a substantially flat 'portion 12e.

These' are adapted'to'project into and closely fit corre# Vspending' cup-shapeddepressions 14 in the adapter 14,' The bolt 1,5 preferably has'a shoulder 15xL by which it may hold -the adapter 14 firmly against the hub flange 13', intowhich itis screwed fand to which 1 it is locked by.'V means o1 thelock-'nuts 15.

17 thereon.

'.lhe 'opposite end of the bolt 15 passes 'through the depression-16 and is threaded to receive the conical-cap nut 17 which has a taper substantially equal to that of the inner surface of the projection 16.

It Will thus be seen that as-the 'cap nuts 17 are screwed down they will force the projections 16 firmly into the depressions 14 and as theyA 'do so thel ears. 1721V pro'.- dueed .by the longitudinal slotsl'b-in the cap nuts Will be pressed inwardly upon .the bolt 15. thereby firmly Alocking the cap nut Practically theentir'e stress on the Wheel is transferred through the projections 1G and thedepressionsv 14a to the adapter l/l 'l The hub is.

which may be made of any suitable ma-v terial. i.

preferably supplied with a huh cap 18 and a central opening 1f) is made in the center of the disk 12 so that the disk can be slipped over the hub cap when assembling or disassembling without removing the hub cap.

Referring now t0 the form shown in l*1 ig. I

4, the hub 20-carries a radial flange 21111 which is :formed a seriesA of depressions 22, Vcach of Which isadapted to receive the corresponding conical projection 23 on the disk 24.

Inthis form I have also provided a cover plate 25 having a radial flange 26' in which 1s formed a series of conical cups 27, each jections 23.

These parts are then held together by means of threads 28 and slotted conical cap nuts 17 as previously described.

adapted to Afit into-one of the conial pro Y lVhile I have sho'Wn and. described .but

two embodiments of my invention, it is to be understood that it is Vcapable of manyv Changes, therefore,"in the construction and .arrangement -rnay be made Without departing from the spirit land scope 'of' the invention as disclosed in the appended claims, in which' 1t 1s mylntention to claiml all novelty. inherent in my invention as broadly as possible in View of the prior art.

What I claim as new, and desire to secure by Letters Patent, is:

In combination with a lwhecl rim and :1 wheel hub having an outwardly extending flange, a relatively thick solid ladapter disposed on the hub in intimato contact therc- U with throughout its thickness and to an e.\'- tent substantially equal to the Width of the rim and abutting said flange, means securing said adapter tosaid flange, the outer ginal edge inolining toward the plane of. the hub flange, and a-disk supporting said rim, said disk intimately Afitting and being sesurface of the adapter adjacent its mar;

cured against the outer surface of said r adapter and having a portion disposed at 'substantially' the same inclination as said Ainclined `surface directly engaging the latterv 'and extending' inwardly to an extent subs/tantially equal to the Width of the rim.
